870-900 / 1000+ resultsresearch Mechanism of hair straightening
Hair can be straightened using different chemicals, not just strong alkali.
research Technique for Processing and Routing Staining of Hair Samples for Histological Study
A new method effectively stains hair samples for study without losing hair sections.
research Special Stains and Immunohistochemical Stains in Hair Pathology
Special and immunohistochemical stains are not routinely needed for diagnosing hair disorders.
research The Degradative Characteristics of Hair in The Water Samples with Altered pH
Hair fibers degrade and change color in very basic water.
research In vitro evaluation of changes of hair fibers subjected to oxidation-reductive straighteners associated with dyeing
Straightening and dyeing damage hair structure.
research When Beauty Turns Toxic: Acute Contact Dermatitis and Kidney Injury Following Hair Straightening
Hair straightening products with glyoxylic acid can cause skin irritation and kidney damage.
research Not always “straight ahead” – A surprising cause of acute kidney injury
Hair straightening treatments can cause serious kidney damage, especially if you have skin issues.
research Internal structure changes in bleached black human hair resulting from chemical treatments: A Raman spectroscopic investigation
Chemical treatments on bleached black hair change its internal structure by breaking and reforming bonds, and treatments with hydrolyzed eggwhite protein help repair it.
research Can hair be protected from oxidative damage during and after bleaching
L-arginine, hydrolysed keratin, and cystine-silanol copolymer can help protect hair from damage during and after bleaching.
research The Potential Teeth Bleaching and Halitosis Prevention Effects of Pediococcus inopinatus THK-30, a Kimchi-Derived Lactic Acid Bacterium: In Vitro Study
A kimchi-derived bacterium could help whiten teeth and prevent bad breath.
research Evaluation of hair fibers properties treated with acid straightener at different pH values
Hair straightening at pH 1.0 improves alignment but weakens hair more than pH 2.0.
research Effect of equilibrium pH on the structure and properties of bleach‐damaged human hair fibers
Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.
research Enzymatic phosphorylation of hair keratin enhances fast adsorption of cationic moieties
Enzymatic phosphorylation of hair keratin improves the effectiveness of hair products with cationic ingredients.
research #3665 Glyoxylic acid induce crystalline nephropathy and hair-straightening products: a case report
Hair-straightening products with glyoxylic acid can cause kidney damage.
research Hydrolyzed Hair Keratin
research The physical and chemical disruption of human hair after bleaching – studies by transmission electron microscopy and redox proteomics
Bleaching hair causes severe structural and chemical damage, including protein loss and oxidation.
research Investigation of pH effect on cationic solute binding to keratin and partition to hair
Solute binding to hair keratin is mainly driven by hydrophobic interactions and changes with pH.
research Action of Nucleophilic Reagents on Hair Keratin
Nucleophilic reagents break down hair keratin, forming more lanthionine and lysinoalanine than in wool.
research Biomechanics of chemically treated hair for continuous 1D strands
NaOH treatment improves hair strength and suitability for textiles.
research Effect of Heat Treatment on Human Hair Keratin Film
Keratin films can measure hair heat damage.

A new method using poly(ethylene imine) improves hair dyeing at lower temperatures with better color retention.
research DSC-investigations of alpha-keratins and the specific effects of chemical treatments on human hair
Chemical treatments weaken hair's thermal stability and structure.
research Optical coherence tomography to evaluate the effects of oxidative hair dye on the fiber
Oxidative hair dye changes hair color and structure but doesn't weaken it.
research The science of color: How chemical dyeing processes transform hair structure
Oxidative dyes damage hair more than semi-permanent dyes, but new technologies help protect hair while coloring.
